tires, and has or one of its objects to i1nprove the construction and increase the efii ciency and utility of devices of this charactor.

Another object of the invent-ion is to provid-e a device of this character which operalles ell'ectually to prevwhich will not injure the tire casing.

, With these and other objects in view, the invention consists in certain novel features of construction, es hereinafter shown and described and then specifically-pointed out in .the claims; and in the drawings illus trativc of the preferred embodiment of the invention- Figure 1 is a side elevation of an automobile wheel with the ii'nprovernent applied` Fig. 2 is a transverse section on the line 2--2 of Fig. 1,

Fig, 3 is u transverse section on the liuc l 3-3 ofiFig. 1,

Figs. 1a and l are enlarged detail longi tudinnl 'sections showing different forms of connections between sections of the device.

The improved device may be applied without innterial structural change to tire casings oi" various` sizes, and, comprises side members formed of a plurality of ser,- mental sections hingedly united at their confronting ends and bearing against the opposite sides of the tire casi'ng. 4The segnicntal sections are indicated by the charac ter 10, und will hr,- sullicient in number to en tirclv encircle the tire casing, represented ut 11. The men'ihcrs lO ure' curved to correspond to the curvature of the tire casing und euehmeiubcr is provided with a slot 12 at one end and a tongue 13 extending from the opposite end. The tongue of each section 10 is ada ted to be inserted tlnouh the slot 12 o the adjacent section an bent over the terminal of the same as illustrated in Fi 1. The terminals of the bands pro duce 'by connecting the sections are without the tongues but rovided each with u Slot. A lisait-ie f .npling strip 14 is inserted Spe'cication of Letters Patent.

through the slot-s' at the said endsof the hands und doubled on itself to flexibly oonnect the bands usshownin Fi 'Each 'section 10 is provided with=a-=on litudinal slot 15 ,as shown. The slots"15p the sections lnay be engaged by straps or ba'ds 16 extending over the casing 1 1, the ends 4of the straps 16 being slightly reduced to-pro' duce tongues adapted to be bent around the material between the slots 15 and the outer edges of the sections as shown in Fig. 3. By this means the hingedly united veide members are coupled over the casing at opposite pair of the'remaining segmental sections at each side of the casing are united by diagonally directed straps 17-18, crossin each other intermediate their ends centra ly of the tire. VFor instance the strap 1f( .is passed sides` of the uniting straps 14. Each at one end through the slot 15 of one of the sections 10 and bent over'the `material 'of the section externally 'of the slot, and thence extended obliquely over the casing and similnrly coupled to the slot 15 ofthe next section nt the opposite side of the casing. e other strap 18 is passed at one end t irougli the slot l5 of the next sectionlO and thence extended ohliquely over the casing in the opposite direction from the first-mentioned obliquely directed strap and crossing the same intermediate the ends, and coupled through the slot of the adyacent section at the opposite side of the casing. The onally directed straps thus etfectually brace and support. the se mental sections in position und coact wit the straps 16 to prevent skidding or slipping of the wheel upon muddy or inclined roads or in soft or sandy roads. Suitehly formed ground-engaging spurs l.) are cfmnected to the straps 16. A t their crossing points cach pair of the straps 417---18 are united a similar spur 20,

instance six 31s shown, are provided with roo , shape of the tire casing and therefore will reduce abrasion thereof when in use. Tic improved device is sim 1e in construction and can be ineli'pensive y manufactured of relatively small portions of sheet metal or steel. The attachment, includin the grounden gagin spurs2 when ap lie to an automobilew eel, will eil'ectua ly prevent skiddin or slipping u n muddy or sotroads, an will t us amp y protect theoccupants of the automobile.

Havin thus described the invention, what is'claime as new is:

1. An anti-skidding device com rising not spacedside members each formed o a plurality of segmental sections hingedly united and adapted to bear against the o osite sides of a tire casing, and a plura ity of members cou led at their ends to certain of the segments, sections and extending iii reversely oblique directions over the casing and crossing at the junction of adjacent sections.

2. An anti-skiddin device comprising spaced side members a apted to bear against the op osite sides of atire casin and each forme of a plurality of pivota ly united segmental sections, transverse straps connectin certain of the segmental sections of the si e members, other straps extending in reversely oblique directions over the tirc casing and connected with other of said segmental sections 'the last-mentioned straps crossing at the junction of adjacent sections and all of said straps being provided with traction devices.

' 3. The combination with a wheel including a felly and tire, of an anti-skidding dcvice coinpi'ising spaced side members boaring against the opposite sides ofthe tire and each formed of a plurality of pivotally united sections, anti-skiddng members conpled at their ends to certain of the se nien tal sections and'ex'tendin in reverse y oliiique directions over the tire` and crossing at the junction'of adjacent sections, and means for securing the side mcmebeis in position on the tire.

4. The combinationv w'itlia wheel including a felly and tire, of an anti-skidding device com. 'ising spaced members bearing against t 'e opposite sides of the tire and each-formed of u pluraiity ofpivotally cnnected segmental sections, there being longitudinal slots formed in the several seg:- mental sections transverse straps fastened in certain of the longitudinal slots, other straps extending over the tire and having their ends fastened in other of the longitudinal slots in said sections, and means for securing the device in position on the` ti rc.
